Ring and module theory: To the connection between C1 and a modified form of C1 and to the significance of C2 and semi-I-regularity for exchange properties
- I introduce a stronger version of CS-modules which lies between CS- and quasi-continuous modules. Moreover I analyze modules with the property C2 that are not necessarily continuous or auto-invariant. Here some results also hold for large restricted modules, which is a weaker property compared to C2. Finally I introduce the definition of semi-I-regular modules as a generalization of the definition of semiregular modules and show that every semi-I-regular module has the finite exchange property and even the exchange property if it further is a module with LE-decomposition or a Utumi module.
